Magnetoactive binuclear copper(II) complexes based on β-aminovinylimines

Magnetoactive binuclear copper(II) complexes based on β-aminovinylimines β-Aminovinylimines containing bulky substituents at the donor nitrogen atoms and copper(II) chelates based on them were synthesized. The compounds were studied by single crystal and powder X-ray diffraction, EXAFS, NMR, EPR, and UV/Vis spectroscopy, and magnetochemistry.

Abstract

β-Aminovinylimines containing bulky substituents at the donor nitrogen atoms and copper(II) chelates based on them were synthesized. The compounds were studied by single crystal and powder X-ray diffraction, EXAFS, NMR, EPR, and UV/Vis spectroscopy, and magnetochemistry. The complexes with halide bridges exhibit a ferromagnetic type of spin-spin interaction. The metal chelate containing a phenyl substituent in the γ-position of the aminovinylimino ligand absorbs atmospheric oxygen in a methylene dichloride solution, which gives rise to a dimer with oxygen bridges exhibiting an antiferromagnetic type of spin-spin interaction.
